Severe flu season straining the resources of ERs around the country

With more than half of U.S. states experiencing high levels of flu-like illness -- and flu activity continuing to rise, ERs across the country are seeing a surge in business -- and some are struggling to keep up.

Currently, 29 states and New York City are reporting high levels of influenza-like-illness (ILI), and another nine states are reporting moderate levels of ILI. This season, 18 children have died from flu-associated deaths.

This year's predominant flu (76 percent) is very similar to a type that caused a severe season in 2003-2004, when the flu shot wasn't a good match and there were more than 40,000 associated deaths, said Dr. Marc Siegel, a member of the Fox News Medical A Team.

Illinois has been hit the hardest, according to the Illinois Department of Health; and 11 Chicago-area hospitals are now on bypass status, meaning they are so swamped with flu patients, they have to turn sick people away.

Melaney Arnold, spokeswoman for the Illinois Dept. of Health, said nearly 150 people have been admitted to intensive care units with the flu this season, and five have died.

Northwestern Medical Center in Chicago is one example of a hospital on bypass status. So if you're in an ambulance because you have the flu, this hospital will have to turn you away. That doesn't mean people can't walk in there and still get treatment if they're OK to do so, but it's going to be a long wait.

The Advocate Good Samaritan Hospital in Downers Grove, Ill., reported that its emergency room has up to a three-hour wait, and a Good Samaritan doctor described the situation as "chaotic."

"It's not like you can just see them and out the door they go. They're here for a while unfortunately, getting treatments," said Dr. Tom Mullin of Good Samaritan. "Most of them we can fortunately discharge them home and treat them as an outpatient. But, it's wreaking havoc on every emergency department in the city and the suburbs, I'll tell you that."

Doctors are advising patients to take anti-virals, like Tamiflu, as soon as symptoms start. Symptoms include fever, cough, sore throat, fatigue, nasal congestion and muscle aches. 

According to the CDC, it is likely the increased flu activity will continue for a while.  Based on the last 10 flu seasons, ILI remained at or above baseline for about 12 weeks – and up to 16 weeks during the 2005-2006 season. ILI remained above baseline for 19 weeks during the 2009 H1N1 pandemic.

Mary Anderson, infection control manager at Edward Hospital in Chicago, said the hospital normally sees an average of 200 cases per season. But as of last week the hospital already has seen more than 260 confirmed cases.

In Rockville, Md., emergency room visits are up 20 to 50 percent, according to Dr. Michael Kerr, chief of staff and chairman of the department of Emergency Medicine at Medstar Montgomery Medical Center in Olney, according to Kerr said the problem is area-wide, and extra doctors and nurses are on-hand to deal with swamped waiting rooms.

In Pennsylvania, Lehigh Valley Hospital-Cedar Crest has set up a 'flu tent' to treat the overwhelming amount of patients coming through, according to

Terry Burger, hospital director of infection control at Lehigh, said, "If we can remove them from the main ED and put them in environment where everyone is masked and everyone can be protected, it's safer for them and certainly safer for the staff."
